RESEARCH

LARGE UNDERGROUND ROOMS
Problems raised: Are there particular geological and hydrogeological environments that explain the presence of gigantic natural underground volumes? Would it be possible to free up similar volumes to build underground nuclear power plants?
This subject gave rise to a geology thesis financed by Electricité de France: "Research on the digging and stability of large underground karst volumes. Applications to the digging of large artificial cavities". A mission was then organized in Borneo where the largest underground room in the world is located.
The results are published in the following works:

UNDERWATER SOURCES
Along the Mediterranean coasts there are high-flow underwater springs that are not used because they are brackish. Their study has helped to understand the mechanism of salinity acquisition. It is linked to the drying up of the Mediterranean about 6 million years ago.

EARTHQUAKES IN CAVES
Caves preserve the memory of the events they have experienced for hundreds of thousands of years. Just as the paintings of prehistoric men have retained their freshness until today, the traces left by earthquakes or tectonic movements are preserved there.

CAVES AND VOLCANOES OF MADAGASCAR
In the north of Madagascar, Ankarana is a limestone plateau with a surface bristling with countless rocky needles. Within it lies a network of caves over a hundred kilometers long. The genesis of the plateau and these caves is linked to the presence of intense volcanism.
